How Law Firms Should Handle Clients Who Need to Sign by Mark

A California Notary Guide for Attorneys & Legal Professionals

When a client cannot physically sign their name, law firms must act carefully, lawfully, and efficiently. In California, this situation requires a Signing by Mark, a process governed by strict rules from the California Secretary of State. When handled incorrectly, it can invalidate documents, delay filings, or expose firms to unnecessary risk.

This guide explains how law firms should handle Signing by Mark notarizations in California, what the law requires, and why working with an experienced mobile notary matters—especially for time-sensitive legal documents.

What Is a “Signing by Mark” in California?

A Signing by Mark occurs when a signer is unable to write their full signature and instead signs using a mark, such as an “X” or another symbol. However, California does not treat this as a casual alternative. Instead, the law requires additional safeguards to protect the signer, the notary, and the integrity of the document.

According to the California Secretary of State Notary Public Handbook, a Signing by Mark requires:

  • The signer to make their mark in the presence of the notary

  • Two impartial witnesses to observe the signing

  • Each witness to sign their own name on the document

  • The notary to record all details accurately in the notary journal

Because these steps must be followed exactly, law firms should never attempt to “simplify” this process.

Why Law Firms Must Handle Signing by Mark Carefully

First and foremost, improperly notarized documents can be rejected by courts, county recorders, lenders, or government agencies. Moreover, mistakes often surface after deadlines pass—when correcting them becomes costly or impossible.

Additionally, law firms face heightened scrutiny. Judges, opposing counsel, and auditors expect absolute compliance. Therefore, handling a Signing by Mark correctly protects:

  • The client’s legal rights

  • The enforceability of the document

  • The firm’s professional reputation

For this reason alone, outsourcing to an experienced mobile notary who understands Signing by Mark notary law in California is a best practice—not a convenience.

Common Scenarios Where Signing by Mark Is Required

Law firms frequently encounter Signing by Mark situations in cases involving:

  • Elderly clients

  • Injured or hospitalized individuals

  • Clients with neurological or motor impairments

  • End-of-life planning

  • Power of Attorney documents

  • Trusts, wills, and estate planning

  • Settlement agreements

In each scenario, speed matters—but compliance matters more.

What Law Firms Should Do Before Scheduling a Signing by Mark

To avoid delays, law firms should prepare in advance. Specifically:

  1. Confirm the client’s inability to sign

  2. Confirm the document allows Signing by Mark

  3. Arrange two impartial witnesses (the notary cannot act as a witness)

  4. Hire a notary experienced with Signing by Mark notarizations

This is where many firms run into trouble. Not all notaries are comfortable—or properly trained—with Signing by Mark procedures.
